いられているが、水洗い又は洗濯により香料が脱落しや
すく、又揮散による香料の減少速度が速いため芳香が持
続しない等の問題点を有するものであった。Conventionally, methods for imparting fragrance to fibers include adsorbing or adhering fragrances to the final textile product through post-processing, but the fragrances tend to fall off when washed with water or washing, and the rate of reduction of fragrances due to volatilization is fast. Therefore, there were problems such as the fragrance not lasting.
そして、この問題点は、特に香料として天然の森林材か
ら採取される天然精油及び天然精油から単離される成分
を用いた場合、天然精油成分のほとんどが沸点１５０〜
１９０℃のモノテルペン或いはジテルペン化合物である
ため、空気中への揮散が早くその傾向が顕著であった。This problem is especially true when using natural essential oils collected from natural forest materials or components isolated from natural essential oils as fragrances, as most of the natural essential oil components have a boiling point of 150-
Since it is a monoterpene or diterpene compound at 190°C, it volatilizes quickly into the air, and this tendency is remarkable.
そこで、本発明者等は、特願昭６０−３８４１６号で開
示した如く、芯部に天然精油を練り込んだ、第５図に示
した様な断面形状の中空芯鞘型複合繊維を提案したがな
お、芳香の持続性に於いてより向上させることが必要で
あった。Therefore, as disclosed in Japanese Patent Application No. 60-38416, the present inventors proposed a hollow core-sheath type composite fiber having a core portion kneaded with natural essential oil and having a cross-sectional shape as shown in Fig. 5. However, it was necessary to further improve the persistence of the fragrance.
本発明の目的は従来の芯鞘型複合繊維よりも芳香の持続
性に優れた中空多芯芯鞘型複合繊維を提供するものであ
る。An object of the present invention is to provide a hollow multi-core sheath-core type conjugate fiber which has superior fragrance persistence than conventional core-sheath type conjugate fibers.
本発明は、繊維断面の中心に中空部分を有する中空芯鞘
型複合繊維であって、香料を含有した芯部が複数個存在
し、かつ各々の芯部が中空部分に露出させることにより
、芯部からの急激な香料の揮散を抑え、芳香の持続性を
向上せしめるものである。The present invention is a hollow core-sheath type composite fiber having a hollow portion at the center of the fiber cross section, and has a plurality of core portions containing a fragrance, and each core portion is exposed to the hollow portion. This suppresses the rapid volatilization of fragrance from the body and improves the sustainability of the fragrance.
以下本発明の詳細な説明する。The present invention will be explained in detail below.
本発明の中空多芯芯鞘型複合繊維において、芯部に練り
込み等により含有された香料は中空部分を介して外気に
発散されるが、その発散の速度は中空部分に露出してい

さくすることが芳香の持続性を向上させる上で重要であ
る。In the hollow multicore sheath-type composite fiber of the present invention, the fragrance contained in the core by kneading or the like is released into the outside air through the hollow part, but the rate of release is determined by the area exposed to the hollow part. increases in proportion to. In other words, it is important to reduce the area of the exposed portion in order to improve the sustainability of the fragrance.
本発明に於いては芯部を互いに接触させることなく複数
個とし、芯部の中空部分への露出面積を小さくしたもの
である。In the present invention, a plurality of core portions are provided without contacting each other, and the area exposed to the hollow portion of the core portion is reduced.

数が６個以上の場合は第１図←１に示したように芯部が
互いに接し、中空部分に露出した芯部の面積が大きくな
り好ましい芳香の持続性が得られないためである。If the number of core parts is multiple, the number is specified in special i71:
Although it is not determined, from the viewpoint of process passability and the rate of volatilization of the fragrance depending on the exposed area of the core, the case of 4 as shown in No. 1) is the most preferable.The reason is that the number of cores is If there are 2 or less, the cross section of the fiber is the first
The shape will be as shown in Figure A), and the length of the L portion will be shortened, resulting in yarn breakage during spinning and poor process stability.In addition, if the number of cores is 6 or more, as shown in Figure 1←1. This is because the core parts touch each other, and the area of the core part exposed to the hollow part becomes large, making it impossible to obtain a desirable fragrance persistence.

性が不充分となる。fFR1! The area ratio of the hollow portion in the cross section, ie, the hollowness ratio, is required to be 5% or more. If it is less than 5%, the volatilization of the fragrance into the outside air will be small and the fragrance release effect will be insufficient. Another 20%
If it exceeds this amount, the fragrance will largely volatilize into the outside air and the fragrance will not last long enough.
芯部を構成する重合体は、湿式、乾式、或いは溶融紡糸
可能な重合体であれば特に限定さｎないが、工業的な製
造の容易さからは溶融紡糸可能な熱可塑性重合体である
のが好ましい。The polymer constituting the core is not particularly limited as long as it is a polymer that can be wet-spun, dry-spun, or melt-spun, but from the viewpoint of ease of industrial production, a thermoplastic polymer that can be melt-spun is preferred. is preferred.

It is a monoterpene or diterpene compound at 90°C and has poor heat resistance and is easily evaporated or decomposed by heat.
Among thermoplastic polymers, it is preferable to use a polymer having a particularly low melting point (softening point), disperse and mix the fragrance at a temperature of 0.degree. C., and perform conjugation melt-spinning at a low temperature.
また、この芯部な構成する重合体は水分によって加水分
解しない重合体であるのが好ましい。Further, the polymer constituting the core portion is preferably a polymer that does not hydrolyze with moisture.
香料を乾燥し、かつ乾燥状態を保ったまま重合体に分散
混合させるのは工業的に極めて複雑な操作が必要であり
、経済的でないからである。This is because drying a perfume and dispersing and mixing it into a polymer while maintaining the dry state requires extremely complicated industrial operations and is not economical.

鋸出し、芳香の持続性が損なわれることになる。The difference in melt viscosity between the polymer constituting the core and the polymer constituting the sheath when melted and discharged is an important point in obtaining the hollow multicore sheath-type composite fiber of the present invention. When the polymer is arranged in the core part and the polyester polymer is arranged in the sheath part, M of the polyethylene polymer. The relative viscosity of the polyester polymer (metacresol, 25 min.) is in the range of 0.5 to 25.
°C) is required to be in the range of 1.55 to 1.70, and if the combination of polymers is not in the above range, no hollow portion will be formed, or a hollow portion will be formed, but
A portion of the core, which is dispersed in a plurality of pieces, is not only exposed in the hollow part, but also directly appears on the outer surface of the fiber as shown in FIG. 4, which impairs the persistence of the fragrance.
本発明に於ける芯部及び鞘部を構成する重合体の比率は
容積比で、芯部：鞘部が２０：８０〜５０ ： ５０の
範囲であることが必要である。In the present invention, the ratio of the polymers constituting the core and sheath in terms of volume ratio is required to be in the range of 20:80 to 50:50.
芯部の比率が５０を越えると芯鞘構造をきれいに形成さ
せるのが難かしくなり、また芯部の比率が２０未満の場
合、芯部重合体へ含有せしめる香料の配合量が減って放
香効果が不充分となる。If the ratio of the core exceeds 50, it becomes difficult to form a neat core-sheath structure, and if the ratio of the core is less than 20, the amount of fragrance contained in the core polymer decreases, resulting in a poor fragrance release effect. becomes insufficient.

は０．５〜４． Ｏｗｔ％であることが必要である。In addition, unnecessarily increasing the amount of fragrance contained in the polymer arranged in the core will reduce the stability of melt spinning and increase thread breakage due to foaming, so the amount of fragrance mixed and dispersed in the polymer arranged in the core. is 0, 1-10. Owt%, preferably 0.5-4. It is necessary that the amount is Owt%.
芯部の重合体に含有せしめる香料は、合成香料であって

くなる。Further, the boiling point of the fragrance at normal pressure must be 150'C or higher. This means that when the temperature is below 150°C, the type of polymer constituting the sheath of the hollow multicore sheath-type composite fiber of the present invention is limited to an extremely narrow range, and the type of polymer used in the fiber is limited to a very narrow range, such as polypropylene, polyamide, polyester, etc. It becomes unusable.

でありても勿論差支えない。The type of scent of the fragrance used in the present invention is not particularly limited, but for example, when mixed with cotton padding for mattresses, comforters, and pillows, essential oils collected from coniferous trees are expected to have a calming scent and have an effect similar to forest bathing. When mixed with cotton stuffing for stuffed animals, fruits such as strawberry IJ + and pineapple, which children like, are recommended, but other scents such as flowers and citrus fruits are also recommended. Of course I don't mind.

While applying the fragrance of this plant essential oil to bedding, interior or home interior materials, and indoor equipment,
Various attempts have been made to obtain the same health benefits as "aromatherapy," but the plant essential oil components used in aromatherapy are composed of an extremely large variety of compounds. In order to truly obtain aromatherapy effects, it is preferable to use a combination of specific natural essential oils and components isolated from natural essential oils.
